Perception plays a dominant role in an intelligent system -- an animal or machine. Computational sensors mimic one aspect of biological systems: they tightly integrate computation and sensing to improve performance and achieve new capabilities. The computational sensor is a new and exciting concept that offers a range of research topics:

applications; apply these integrated circuits in a system that intelligently interacts with the environment and/or human.

The sensors I have built so far are vision sensors. They detect images and compute useful quantities from those images very quickly. My specific projects include: a sorting computational sensor which senses an image and sorts pixel values by their intensities, a tracking computational sensor which selects and tracks visual stimulus within the field of view, an eye tracking computational sensor, and a road-following computational sensor.
